Electrovolt-scale backgrounds from surfaces
Alan E. Robinson
Recent results from the SENSEI experiment show that a cut on event clustering can reduce low-energy excesses in their eV-sensitive calorimeter. This hints at the role of surroundin…
XENON1T observes tritium
Alan E. Robinson
XENON1T recently reported an excess of low-energy electron recoil events that may be attributable to either new physics or to the radioactive decay of tritium. It is likely that hy…
Constraints on low-mass, relic dark matter candidates from a surface-operated SuperCDMS single-charge sensitive detector
SuperCDMS Collaboration, D. W. Amaral, T. Aralis +116
This article presents an analysis and the resulting limits on light dark matter inelastically scattering off of electrons, and on dark photon and axion-like particle absorption, us…
Comment on A dark matter interpretation of excesses in multiple direct detection experiments [arXiv:2002.06937]
Alan E. Robinson, Émile Michaud
In their recent preprint [arXiv:2002.06937], Kurinsky, Baxter, Kahn, and Krnjaic assume an unphysical ionization yield for plasmon excitations in order to claim a possible dark mat…
Developing a Bubble Chamber Particle Discriminator Using Semi-Supervised Learning
B. Matusch, C. Amole, M. Ardid +70
The identification of non-signal events is a major hurdle to overcome for bubble chamber dark matter experiments such as PICO-60. The current practice of manually developing a disc…

We report the result of a blinded search for Weakly Interacting Massive Particles (WIMPs) using the majority of the SuperCDMS Soudan dataset. With an exposure of 1690 kg days, a si…
The coherent photon scattering background in sub-GeV/ direct dark matter searches
Alan E. Robinson
Proposed dark matter detectors with eV-scale sensitivities will detect a large background of atomic (nuclear) recoils from coherent photon scattering. This background climbs steepl…
Projected Sensitivity of the SuperCDMS SNOLAB experiment
